Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to an automated external defibrillator. Background Technology
[0002] A defibrillator is a medical device that delivers a strong pulse of electrical current to the heart to treat cardiac arrest or arrhythmia through an electric shock. In the event of cardiac arrest, defibrillation and cardiopulmonary resuscitation (CPR) within the crucial "golden four minutes" are effective ways to prevent sudden cardiac death.
[0003] The two most common types of defibrillators are AEDs (automated external defibrillators) and MEDs (manual external defibrillators). MEDs are manually operated defibrillators, typically used in professional medical settings such as hospitals, emergency rooms, and ambulances. They are usually used by professional medical personnel who can deliver electric shocks based on the patient's specific condition.
[0004] As an emergency medical device used in public places, ambulances, and homes, the use of AEDs is subject to uncertainty. During storage or use, the device may be subject to adverse conditions such as being dropped, knocked over, or trampled, which can easily damage the main functional components inside the AED (such as the screen, energy storage capacitor, and circuit board).

[0052] When an automated external defibrillator (AED) is subjected to impacts such as drops or collisions, taking the front housing assembly as an example (where the front housing is the first to be impacted), the front housing assembly transmits the impact force to the circuit board (rigid board) of the first circuit board. The circuit board of the first circuit board then transmits the force to the mounting bracket, which in turn transmits the force to the rear housing assembly. Simultaneously, the connection between the front and rear housing assemblies can also directly transmit the force. Therefore, this method helps reduce the degree of deformation of the front and rear housing assemblies, reduces the probability of the front and / or rear housing assemblies impacting the electronic components on the internal first and / or second circuit boards during deformation, reduces the likelihood of damage to the first and / or second circuit boards, and improves the AED's impact resistance.

Detailed Implementation
[0071] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0072] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.
[0073] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.
[0074] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.
[0075] An automated external defibrillator (AED) is a medical device used to treat cardiac arrest or arrhythmias. In this application specification, "automated external defibrillator" and "defibrillator" refer to the same object. An AED restores a normal heart rhythm by applying an electric shock to the heart. To achieve this function, it includes a housing 1 serving as the device's outer shell. The space enclosed by the housing 1 houses components such as a circuit board and a storage capacitor. When the AED detects the need for defibrillation, it stores electrical energy in the storage capacitor 3 via a charging circuit. The AED then releases this energy from the storage capacitor to the patient's chest through electrodes to deliver an electric shock.
[0076] As an emergency medical device used in public places, ambulances, and homes, the use of AEDs is subject to uncertainty. During storage or use, the device may be subject to adverse conditions such as being dropped, knocked over, or trampled, which can easily damage the main functional components inside the AED, especially the electronic components on the circuit board.
[0077] Therefore, this application provides an automated external defibrillator (AED). Please refer to [link to AED embodiment]. Figures 1 to 7 It includes a housing 1, a first circuit board 21, a second circuit board 22, an energy storage capacitor 3, and an insulating mounting bracket 4.
[0078] Please see Figure 1 and Figure 2 The housing 1 includes a front housing assembly 11 and a rear housing assembly 12, which are connected front to back along a first direction. Exemplarily, the first direction can be understood as the thickness direction of the automated external defibrillator. In this embodiment, taking the thickness direction of the automated external defibrillator as an example, the first circuit board 21 and the second circuit board 22 are sequentially arranged from the front to the back of the housing 1.
[0079] The first circuit board 21, the energy storage capacitor 3, the mounting bracket 4, and the second circuit board 22 are all disposed within the housing 1. The first circuit board 21 is directly or indirectly connected to the front housing assembly 11. Specifically, the front housing assembly 11 and the rear housing assembly 12 together form an inner cavity, in which the first circuit board 21, the energy storage capacitor 3, the mounting bracket 4, and the second circuit board 22 are all housed.
[0080] The second circuit board 22 is electrically connected to the first circuit board 21. It should be noted that the electrical connection between the first circuit board 21 and the second circuit board 22 may include high-voltage connections and / or low-voltage signal connections. The specific connections included depend on the functional design of the two circuit boards in the specific embodiment.
[0081] The first circuit board 21 and the second circuit board 22 are arranged at intervals along a first direction, that is, the first circuit board 21 and the second circuit board 22 can be parallel to each other. The orthographic projections of the first circuit board 21 and the second circuit board 22 onto the same plane along the first direction at least partially overlap.
[0082] The energy storage capacitor 3 is electrically connected to the first circuit board 21 and / or the second circuit board 22. That is, at least one of the first circuit board 21 and the second circuit board 22 is electrically connected to the energy storage capacitor 3. In this way, the charging and discharging of the energy storage capacitor 3 can be realized. As for which circuit board the energy storage capacitor 3 is specifically connected to, it also depends on the functional design of the two circuit boards in the specific implementation.
[0083] The automated external defibrillator in this embodiment has a first circuit board 21 and a second circuit board 22. However, this embodiment does not limit the automated external defibrillator to only having two circuit boards. In fact, based on the inventive concept, the automated external defibrillator may include other circuit boards in addition to the first circuit board 21 and the second circuit board 22.
[0084] It should be noted that circuits are provided on both the first circuit board 21 and the second circuit board 22.
[0085] Mounting bracket 4 is electrically insulated, meaning it is non-conductive. For example, mounting bracket 4 may be made wholly or partially of electrically insulating material.
[0086] Please see Figure 10 The mounting bracket 4 is located on the side of the first circuit board 21 facing the second circuit board 22 and is fixed to the first circuit board 21. That is, the mounting bracket 4 and the first circuit board 21 are relatively fixed to each other. The first circuit board 21 provides the mounting position and mounting support for the mounting bracket 4, and the two can transmit forces.
[0087] The second circuit board 22 is fixed to the mounting bracket 4, that is, the mounting bracket 4 provides the mounting position and mounting support for the second circuit board 22.
[0088] Since the second circuit board 22 is fixed on the mounting bracket 4, and the mounting bracket 4 is fixed on the first circuit board 21, the first circuit board 21, the mounting bracket 4, and the second circuit board 22 can be assembled into a whole, realizing modular design and facilitating modular assembly.
[0089] The rear shell assembly 12 has a supporting structure that directly or indirectly abuts against the mounting frame 4, and the rear shell assembly 12 and the second circuit board 22 are spaced apart so that the rear shell assembly 12, the mounting frame 4, the first circuit board 21, and the front shell assembly 11 form an impact force transmission path.
[0090] When an automated external defibrillator (AED) is subjected to impacts such as drops or collisions, taking the front housing assembly 11 as an example where the front housing assembly 11 is the first to be impacted, the front housing assembly 11 transmits the impact force to the circuit board (rigid board) of the first circuit board 21. The circuit board 21 then transmits the force to the mounting bracket 4, which in turn transmits the force to the rear housing assembly 12. Simultaneously, the connection between the front housing assembly 11 and the rear housing assembly 12 can also directly transmit the force. Therefore, this helps reduce the degree of deformation of the front housing assembly 11 and the rear housing assembly 12, reduces the probability of the front housing assembly 11 and / or the rear housing assembly 12 impacting the electronic components on the internal first circuit board 21 and / or second circuit board 22 during deformation, reduces the probability of damage to the first circuit board 21 and / or second circuit board 22, and improves the AED's impact resistance.
[0091] In some embodiments, the circuit on the first circuit board 21 includes a first low-voltage circuit and a first high-voltage circuit. The first low-voltage circuit includes at least one or all of a power supply circuit, a main control circuit, and a parameter circuit.
[0092] The first high-voltage circuit includes a charging and discharging circuit, and the energy storage capacitor 3 is electrically connected to the first circuit board 21.
[0093] The circuitry provided on the second circuit board 22 includes a second high-voltage circuit for converting electrical energy into defibrillation current.
[0094] The power supply circuit is used to provide energy from the battery module to the devices on the automated external defibrillator, and the parameter circuit includes various functional modules.
[0095] The parameter circuit includes various functional modules, such as heart rate detection and waveform analysis. The main control circuit controls the operation and coordination of each functional module. The first high-voltage circuit charges the energy storage capacitor 3 and is electrically connected to the discharge interface. The energy storage capacitor 3 is electrically connected to the first circuit board 21 to obtain the required energy from the first high-voltage circuit. The biphasic wave is an electric shock waveform with good therapeutic effects. The second high-voltage circuit is responsible for generating this biphasic wave current. That is, the first low-voltage circuit and the first high-voltage circuit on the first circuit board 21 are responsible for power supply / control and charging / discharging functions, respectively. The second high-voltage circuit on the second circuit board 22 is responsible for generating the biphasic wave current.
[0096] Through the above circuit layout, the second high-voltage circuit responsible for generating biphasic current is set on the second circuit board 22, and the first high-voltage circuit responsible for charging and discharging functions is set on the first circuit board 21. For automated external defibrillators with different functions, customized designs can be implemented on the first circuit board 21, and the second circuit board 22 can be reused in automated external defibrillators with different functions, thereby improving the reuse rate of the second circuit board 22.
[0097] In some embodiments, please refer to Figure 5 and Figure 6 The first high-voltage circuit includes a transformer 211 and a relay 212. In an embodiment where the energy storage capacitor 3 and the second circuit board 22 (mounting bracket 4) are arranged along a second direction, the transformer 211 and / or the relay 212 are located at both ends of the second circuit board 22 in a third direction, such that when the automated external defibrillator is projected orthogonally along the first direction onto the same plane, the projections of the transformer 211 and the second circuit board 22 do not overlap, and the projections of the relay 212 and the second circuit board 22 do not overlap. However, when projected orthogonally along a third direction onto the same plane, the projections of the transformer 211 and the second circuit board 22 partially overlap, and the projections of the relay 212 and the second circuit board 22 partially overlap.
[0098] Since both transformer 211 and relay 212 are considered tall components in the circuit, meaning they are relatively large in height (the height direction is consistent with the first direction), this typically results in a larger overall circuit board thickness, and consequently, a larger device thickness. Placing the tall transformer 211 and relay 212 on either side of the second circuit board 22 helps integrate them with the mounting bracket 4, making full use of space and resulting in a more compact structural layout.
[0099] In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.
[0100] For example, please refer to Figure 10 The mounting bracket 4 has a receiving groove 41a, the opening of which faces away from the first circuit board 21, and the second circuit board 22 is housed in the receiving groove 41a. The sidewall of the receiving groove 41a protects the second circuit board 22, reducing the chance of other surrounding components scratching the second circuit board 22.
[0101] In some embodiments, the receiving groove 41a is filled with insulating adhesive, which is used to fix the second circuit board 22 and / or the electronic components on the second circuit board 22 to the mounting bracket 4. Filling the receiving groove 41a with insulating adhesive can achieve a fixed connection between the second circuit board 22 and the mounting bracket 4 without the need for screws or welding. The second circuit board 22 and the mounting bracket 4 are less likely to move relative to each other, the connection is reliable, and the insulating adhesive can also protect and electrically insulate the circuit on the surface of the second circuit board 22, reducing the probability of damage to the circuit on the second circuit board 22.
[0102] Specifically, during the assembly process, the second circuit board 22 is placed into the receiving groove 41a through the opening 11a, and then glue is poured into the receiving groove 41a until the glue cures.
[0103] The specific shape of mounting bracket 4 is not limited.
[0104] For example, please refer to Figure 10 The mounting frame 4 includes a mounting frame 41 and a plurality of connecting posts 42. The mounting frame 41 and the first circuit board 21 are spaced apart along a first direction, and the second circuit board 22 is fixed to the mounting frame 41. The aforementioned receiving groove 41a is formed in the mounting frame 41. The plurality of connecting posts 42 are located between the mounting frame 41 and the first circuit board 21, and connect the mounting frame 41 and the first circuit board 21. In this embodiment, the mechanical connection between the mounting frame 41 and the first circuit board 21 is achieved through the connecting posts 42, so that the mounting frame 41 and the first circuit board 21 are spaced apart. Therefore, the area of the first circuit board 21 facing the mounting frame 41 can also be used to arrange circuits, improving the surface utilization of the first circuit board 21.
[0105] The number of connecting posts 42 is not limited; for example, there can be one, two, or more. As an example, the outline of the mounting frame 41 in the projection onto a plane perpendicular to the first direction is approximately quadrilateral, and the number of connecting posts 42 is four. The four connecting posts 42 are approximately located at the apex of the quadrilateral, which helps to provide stable support for the mounting frame 41.
[0106] In some embodiments, the first circuit board 21 has mounting holes, and at least one connecting post 42, with its end away from the mounting frame 41, passes through and is fixed in the mounting holes. This improves the structural strength and connection reliability of the connection between the first circuit board 21 and the connecting post 42.
[0107] The fixing method of the connecting post 42 to the mounting hole is not limited. For example, in some embodiments, the connecting post 42 and the mounting hole are interference-fitted to achieve fixing. In other embodiments, the connecting post 42 and the wall of the mounting hole are bonded, welded, or otherwise connected.
[0108] In some embodiments, at least one connecting post 42 may also be provided with a backstop hook at the end away from the mounting frame 41. During assembly, the backstop hook passes through the mounting hole from the side of the first circuit board 21 near the second circuit board 22 and moves to the side of the first circuit board 21 away from the second circuit board 22, thereby abutting against the surface of the side of the first circuit board 21 away from the second circuit board 22, thereby further preventing the connecting post 42 from detaching from the first circuit board 21 in the first direction. The other connecting posts 42 abut against the side of the first circuit board 21 near the second circuit board 22, thereby fixing the mounting bracket 4 relative to the first circuit board 21.
[0109] In some embodiments, please refer to Figure 10 The automated external defibrillator (AED) also includes a conductive post 23, which is at least partially disposed between the first circuit board 21 and the second circuit board 22, and conductively connects the first circuit board 21 and the second circuit board 22. That is, the first circuit board 21 and the second circuit board 22 can be electrically connected via the conductive post 23. This electrical connection can be either a high-voltage or low-voltage connection. The conductive post 23 facilitates the passage of large currents. It should be noted that since the second circuit board 22 is fixed to the mounting bracket 4, and the mounting bracket 4 is fixed to the first circuit board 21, when the AED is dropped or subjected to impact, the force is absorbed through the mounting bracket 4, while the conductive post 23 is largely unaffected by the impact force. This improves the reliability of the electrical connection of the conductive post 23.
[0110] In some embodiments, the connecting post 42 is hollow, and the conductive post 23 penetrates the interior of the connecting post 42, meaning that the conductive post 23 is at least partially housed within the connecting post 42 and extends from one end of the connecting post 42 to the other end. In other embodiments, the mounting frame 4 may include other hollow column structures located between the mounting frame 41 and the first circuit board 21, with the conductive post 23 penetrating the interior of the hollow column structure.
[0111] In other embodiments, the first circuit board 21 and the second circuit board 22 can also be electrically connected by wires.
[0112] In some embodiments, the first circuit board 21, the mounting bracket 4, and the energy storage capacitor 3 are all mounted on the front housing assembly 11. This facilitates the centralized arrangement of the first circuit board 21, the mounting bracket 4, and the energy storage capacitor 3 within the front housing assembly 11, enabling modular design and assembly.
[0113] In some embodiments, the automated external defibrillator includes a display screen 6, a front housing assembly 11 having an opening 11a, the display screen 6 being fixed inside the front housing assembly 11 and exposed outside the opening 11a, and the display screen 6 being located on the side of the first circuit board 21 away from the second circuit board 22. That is, the user can see the display screen 6 through the opening 11a, so that the user can understand the working status of the automated external defibrillator or the patient's physiological parameters, or perform human-machine interaction operations.
[0114] Of course, in other embodiments, the automated external defibrillator may not have a display screen 6.
[0115] In some embodiments, the orthographic projections of the first circuit board 21 and the display screen 6 onto the same plane along a first direction at least partially overlap. This facilitates full utilization of space and improves structural compactness.
[0116] In some embodiments, please refer to Figure 3 , Figure 6 , Figure 7 , Figure 11 The automated external defibrillator also includes a support frame 5, which is disposed within the housing 1 and connected to the front housing assembly 11, for example, by means of screws, adhesive, or other methods. At least a portion of the support frame 5 extends into the gap between the display screen 6 and the first circuit board 21 along a first direction. When the automated external defibrillator is dropped or subjected to impact, even if the first circuit board 21 deforms in the direction close to the display screen 6, the components on the first circuit board 21 are less likely to impact the display screen 6 due to the obstruction of the support frame 5, thereby preventing damage to the display screen 6. In addition, the support frame 5 also helps to enhance the structural strength and rigidity of the front housing assembly 11 at the opening 11a, making the front housing assembly 11 less prone to deformation or cracking at the opening 11a, thereby making the display screen 6 less likely to be damaged by deformation or cracking of the front housing assembly 11 at the opening 11a.
[0117] In some embodiments, please refer to Figure 3 and Figure 11 The support frame 5 and the mounting frame 4 have at least partial overlap in their orthographic projections on the same plane along the first direction. Thus, when the automated external defibrillator is dropped or subjected to impact, the support frame 5 supports the first circuit board 21, thereby enhancing the support provided by the first circuit board 21 to the mounting frame 4 and further improving the impact resistance of the automated external defibrillator.
[0118] In some embodiments, the projection of the display screen 6 is located within the projection range of the support frame 5 in orthographic projection onto the same plane along the first direction. That is, the support frame 5 completely covers the display screen 6 from the back, thus providing more comprehensive protection for the display screen 6 and reducing the probability of impact from the first circuit board 21 and other components to the display screen 6.
[0119] For example, please refer to Figure 8 and Figure 9 The inner surface of the front housing assembly 11 has a mounting surface 11b around the opening 11a. The automated external defibrillator includes a vibration damping structure 13 (see reference). Figure 7 A vibration damping structure 13 is disposed between the support frame 5 and the display screen 6. The support frame 5 holds the vibration damping structure 13 against the display screen 6, thereby holding the display screen 6 against the mounting surface 11b through the vibration damping structure 13. The vibration damping structure 13 serves to dampen vibrations and buffer, protecting the display screen 6. In addition, the support frame 5, through the vibration damping structure 13, holds the display screen 6 against the front housing assembly 11 to prevent the display screen 6 from detaching from the front housing assembly 11. Specifically, in some embodiments, the display screen 6 is directly connected to the front housing assembly 11. When the connection between the display screen 6 and the front housing assembly 11 fails, the support frame 5 acts as a barrier and constraint for the display screen 6, preventing the display screen 6 from detaching from the front housing assembly 11.
[0120] The vibration damping structure 13 can be, for example, made of foam, sponge, fabric, leather, etc., providing both vibration damping and breathable heat dissipation. Of course, the vibration damping structure 13 can also be made of rubber, silicone, etc.
[0121] In some embodiments, the vibration damping structure 13 is generally layered and laid flat on the back of the display screen 6, which helps the support frame 5 to press the vibration damping structure 13 against the back of the display screen 6.
[0122] In some embodiments, the display screen 6 is bonded to the mounting surface 11b using double-sided adhesive, which surrounds the opening 11a. The display screen 6 and the front housing assembly 11 can be connected using this double-sided adhesive. The double-sided adhesive serves to connect the display screen 6 and the front housing assembly 11, as well as to provide cushioning and vibration damping, and also to act as a seal, reducing the likelihood of external moisture, dust, etc., entering the inner cavity of the housing 1 through the gap between the display screen 6 and the mounting surface 11b.
[0123] In this embodiment, double-sided tape refers to a structure that has adhesive function on both sides of the strip-shaped body, and there are no restrictions on the material of the strip-shaped body.
[0124] In some embodiments, please refer to Figure 7 The support frame 5 has at least one rib structure 511 on the side facing the first circuit board 21. The rib structure 511 extends toward the first circuit board 21, and the first circuit board 21 abuts against the rib structure 511. In this way, when the automated external defibrillator is dropped or subjected to impact, there will be almost no relative movement between the first circuit board 21 and the support frame 5, and the two will not collide with each other.
[0125] The first circuit board 21 can be pressed against the rib structure 511 of the support frame 5 by means of the connection force between the first circuit board 21 and the front shell assembly 11. In this way, the first circuit board 21 and the rib structure 511 can be without screws, thereby avoiding the risk of screws passing through the support frame 5 in the first direction and damaging the display screen 6.
[0126] In some embodiments, please refer to Figure 8 and Figure 9 The inner wall of the front housing assembly 11 has protruding ribs 111, which continuously or intermittently surround the opening 11a to form a display screen receiving position, within which the display screen 6 is located. The protruding ribs 111 serve to position and limit the display screen 6. During assembly, the display screen 6 can be placed in the display screen receiving position, thus determining its installation position and enabling rapid positioning. Furthermore, the protruding ribs 111 also help to limit the display screen 6, reducing the likelihood of it shifting on the inner wall surface of the front housing assembly 11. The design of the protruding ribs 111 also helps to increase the structural strength and rigidity of the front housing assembly 11 at the opening 11a, making the front housing assembly 11 less prone to deformation or cracking.
[0127] In some embodiments, please refer to Figure 7 and Figure 11 The support frame 5 includes a plate-shaped body 51 and a protruding edge 53 extending continuously or intermittently from the periphery of the plate-shaped body 51 and abutting against the front housing assembly 11. The plate-shaped body 51 covers the display screen receiving area, and the protruding edge 53 extends along a first direction toward the inner wall of the front housing assembly 11 and engages with the exterior or interior of a protruding rib 111 on the inner wall of the front housing assembly 11, positioning the support frame 5 relative to the protruding rib 111. In this embodiment, the cooperation between the protruding edge 53 and the protruding rib 111 enables rapid positioning of the support frame 5 during assembly. Furthermore, the cooperation between the protruding edge 53 and the protruding rib 111 reduces the probability of the support frame 5 shifting relative to the protruding rib 111 in any direction perpendicular to the first direction (e.g., the second direction, a third direction).
[0128] In some embodiments, the energy storage capacitor 3 and the display screen 6 have at least partial overlap in their orthographic projections onto the same plane along a first direction. This allows for full utilization of the space on the back side of the display screen 6 to mount the energy storage capacitor 3, improving the space utilization of the internal cavity. At least a portion of the support frame 5 extends into the gap between the energy storage capacitor 3 and the display screen 6 along the first direction. When the automated external defibrillator is dropped or subjected to an impact, even if the energy storage capacitor 3 moves towards the display screen 6 due to the impact, the support frame 5 acts as a buffer against the energy storage capacitor 3, reducing the probability of the energy storage capacitor 3 impacting the display screen 6.
[0129] In some embodiments, the first circuit board 21 and the energy storage capacitor 3 are arranged at intervals along the second direction, meaning that the first circuit board 21 and the energy storage capacitor 3 do not contact each other in the second direction. The energy storage capacitor 3 extends along the third direction. The support frame 5 overlaps with the orthographic projection of the energy storage capacitor 3 onto the same plane along the first direction, which helps to make full use of space and makes the structural arrangement more compact.
[0130] In some embodiments, the support frame 5 includes a plate-shaped body 51 and a blocking portion 52, the blocking portion 52 being located on the side of the plate-shaped body 51 closer to the energy storage capacitor 3. The plate-shaped body 51 is located between the first circuit board 21 and the display screen 6, and at least a portion of the blocking portion 52 extends beyond the first circuit board 21 along a first direction and extends close to the energy storage capacitor 3. When the automated external defibrillator is dropped or subjected to impact, even if the energy storage capacitor 3 is impacted and moves in a second direction closer to the first circuit board 21, the blocking portion 52 acts as a barrier to the energy storage capacitor 3, reducing the probability of the energy storage capacitor 3 impacting the first circuit board 21.
[0131] In some embodiments, please refer to Figure 3 , Figure 7 and Figure 11 The blocking part 52 has a first concave surface 52a on the side facing the energy storage capacitor 3. The first concave surface 52a extends and curves along the outer periphery of the energy storage capacitor 3. The first concave surface 52a can increase the circumferential contact length between the blocking part 52 and the energy storage capacitor 3, and has a better blocking effect on the energy storage capacitor 3.
[0132] In some embodiments, please refer to Figure 3 and Figure 9 The inner wall of the housing 1 also has a second concave surface 11c. For example, the inner wall of the front housing assembly 11 has a second concave surface 11c. The second concave surface 11c extends curvedly along the outer periphery of the energy storage capacitor 3, and the first concave surface 52a and the second concave surface 11c are located on opposite sides of the energy storage capacitor 3 along the second direction. In this way, the energy storage capacitor 3 is constrained along the second direction by the first concave surface 52a and the second concave surface 11c, which is beneficial for stabilizing the energy storage capacitor 3 in the installation position.
[0133] It should be noted that the first concave surface 52a can be a continuous concave surface or a discontinuous concave surface defined by the end faces of multiple ribs. These discontinuous concave surfaces can be located on the same virtual cylindrical surface. The second concave surface 11c can be a continuous concave surface or a discontinuous concave surface defined by the end faces of multiple ribs. These discontinuous concave surfaces can be located on the same virtual cylindrical surface.
[0134] In some embodiments, please refer to Figure 3The inner wall of the front housing assembly 11 has a circuit board rib structure 113 corresponding to the area of the first circuit board 21. The circuit board rib structure 113 extends toward the first circuit board 21 and directly or indirectly abuts against the first circuit board 21. The circuit board rib structure 113 can directly contact the first circuit board 21, or a layer of foam or other damping material can be placed between them. The supporting effect of the circuit board rib structure 113 on the first circuit board 21 helps to reduce the deformation of the first circuit board 21 in the direction closer to the front housing assembly 11 when subjected to impact.
[0135] In some embodiments, please refer to Figure 3 and Figure 15 The inner wall of the rear shell assembly 12, corresponding to the area of the energy storage capacitor 3, is provided with a capacitor rib structure 1221. The capacitor rib structure 1221 extends toward the energy storage capacitor 3 and directly or indirectly abuts against the outer peripheral surface of the energy storage capacitor 3 when it is impacted. In this case, the capacitor rib structure 1221 can directly contact the energy storage capacitor 3, or a layer of foam or other vibration damping material can be placed between them. By directly or indirectly abutting the energy storage capacitor 3 with the capacitor rib structure 1221, the movement space of the energy storage capacitor 3 when impacted can be reduced, making it less likely for the energy storage capacitor 3 to deviate from its position and reducing the probability of the energy storage capacitor 3 colliding with other surrounding components.
[0136] In some embodiments, the mounting bracket 4 and the energy storage capacitor 3 are arranged at intervals along a second direction. A baffle structure 123 is formed on the inner surface of the rear housing assembly 12. The baffle structure 123 extends toward the mounting bracket 4 and the energy storage capacitor 3 at intervals along the second direction. The baffle structure 123 and the energy storage capacitor 3 at least partially overlap in their orthographic projections onto the same plane along the second direction. When the automated external defibrillator is dropped or subjected to an impact, if the energy storage capacitor 3 moves along the second direction towards the mounting bracket 4 due to the impact, the baffle structure 123 acts as a barrier, reducing the probability of the energy storage capacitor 3 impacting the mounting bracket 4, thereby reducing the probability of the energy storage capacitor 3 damaging the second circuit board 22.
[0137] In some embodiments, please refer to Figure 14 and Figure 16The rear housing assembly 12 includes an arcuate housing portion 122 and a flat plate portion 121 interconnected along a first direction. The arcuate housing portion 122 protrudes away from the front housing assembly 11. In the first direction, the energy storage capacitor 3 faces the inner side of the arcuate housing portion 122, that is, the inner surface of the arcuate housing portion 122 faces the energy storage capacitor 3. The mounting bracket 4 faces the inner side of the flat plate portion 121, that is, the inner surface of the flat plate portion 121 faces the mounting bracket 4. The arcuate housing portion 122 and the energy storage capacitor 3 overlap in their orthographic projections onto the same plane along a second direction. When the automated external defibrillator is dropped or subjected to impact, the end of the arcuate housing portion 122 near the flat plate portion 121 acts as a buffer against the energy storage capacitor 3, reducing the probability of the energy storage capacitor 3 impacting the mounting bracket 4, thereby reducing the probability of the energy storage capacitor 3 impacting and damaging the second circuit board 22.
[0138] In some specific embodiments, the outer peripheral surfaces of the arc-shaped shell 122 and the energy storage capacitor 3 are designed with contouring, which helps to improve the structural compactness.
[0139] For example, the baffle structure 123 is connected to the arc-shaped shell portion 122, or to the intersection of the arc-shaped shell portion 122 and the flat plate portion 121. The combination of the baffle structure 123 and the arc-shaped shell portion 122 can further enhance the stopping effect on the energy storage capacitor 3 in the second direction and in the direction close to the mounting bracket 4, thereby improving the stopping reliability.
[0140] The connection position of the baffle structure 123 on the rear shell assembly 12 can be as close as possible to the intersection of the arc-shaped shell portion 122 and the flat plate portion 121. In this way, the extension length of the baffle structure 123 can be relatively short, while taking into account the structural strength of the baffle structure 123.
[0141] In some embodiments, the orthographic projections of the baffle structure 123 and the mounting bracket 4 on the same plane along the first direction do not overlap, and the orthographic projection of the baffle structure 123 on the same plane along the first direction is located in the interval between the projections of the mounting bracket 4 and the energy storage capacitor 3. When the automated external defibrillator is dropped or subjected to impact, the baffle structure 123 can both stop the energy storage capacitor 3 in the direction of the second direction towards the mounting bracket 4, and prevent the baffle structure 123 from impacting the mounting bracket 4 along the first direction, thereby protecting the second circuit board 12.
[0142] In some embodiments, please refer to Figure 14 and Figure 16 The rear housing assembly 12 is partially recessed inward (or towards the front housing assembly 11) to form a battery compartment 12a for accommodating the battery module 9. The automated external defibrillator also includes a cover 8 that covers the opening of the battery compartment 12a. In some embodiments, the cover 8 is substantially flush with the flat portion 121. The battery module 9 housed in the battery compartment 12a can be a disposable battery or a rechargeable battery.
[0143] In some embodiments, the battery compartment 12a and the energy storage capacitor 3 are arranged at intervals along a second direction, and the second circuit board 22 and the mounting bracket 4 are disposed in the intervals between the battery compartment 12a and the energy storage capacitor 3 along the second direction, wherein the first direction, the second direction and the extension direction of the energy storage capacitor 3 are perpendicular to each other.
[0144] Because automated external defibrillators (AEDs) need to deliver high-energy defibrillation current to patients, a large energy storage capacitor 3 is required to store the energy for the shock and deliver this high-energy shock when needed. For this reason, the energy storage capacitor 3 in an AED typically has a large volume. The battery compartment 12a is also relatively large. Therefore, it can be understood that arranging the battery compartment 12a, the mounting bracket 4, and the energy storage capacitor 3 sequentially along the second direction can fully utilize the space between the energy storage capacitor 3 and the battery compartment 12a in the second direction to arrange the mounting device, improving space utilization and enhancing the structural compactness of the AED. However, this application is not limited to this; the mounting bracket can also be L-shaped, with the battery compartment 12a, a portion of the mounting bracket 4, and the energy storage capacitor 3 arranged sequentially along the second direction.
[0145] Please see Figure 15 The battery compartment 12a includes a first sidewall 124, the surface of which faces the energy storage capacitor 3 and is close to the mounting bracket 4. Specifically, one surface of the first sidewall 124 faces the battery, and the other surface of the first sidewall 124 faces the mounting bracket 4.
[0146] In some embodiments, please refer to Figure 15 The inner surface of the rear shell assembly 12 is formed with a first reinforcing rib 1211 and the aforementioned retaining rib structure 123. The retaining rib structure 123 and the energy storage capacitor 3 have at least partial overlap in their orthogonal projections onto the same plane along the second direction. One end of the first reinforcing rib 1211 is connected to the first sidewall 124, and the other end is connected to the retaining rib structure 123. The first reinforcing rib 1211 helps to strengthen the structural strength of the first sidewall 124 and the retaining rib structure 123, and also helps to strengthen the structural strength of the flat plate portion 121, making the flat plate portion 121 less prone to deformation when subjected to impact.
[0147] In some embodiments, please refer to Figure 3 and Figure 15 The end of the first sidewall 124 away from the front housing assembly 11 protrudes towards the side near the energy storage capacitor 3, forming a protruding structure 1241. The protruding structure 1241 is configured as at least a part of the abutment structure, that is, the protruding structure 1241 directly or indirectly abuts against the mounting bracket 4. One end of the first reinforcing rib 1211 is connected to the protruding structure 1241, that is, the first sidewall 124 is connected to the first reinforcing rib 1211 through the protruding structure 1241.
[0148] In some embodiments, please refer to Figure 15 The supporting structure also includes a first stiffener 125 and a second stiffener 126, which are arranged at intervals relative to each other along a third direction. A second reinforcing rib 1212 is formed on the inner surface of the rear shell assembly 12. The first stiffener 125, the retaining rib structure 123, the second stiffener 126, and the protruding structure 1241 are sequentially connected to form a polygonal frame. Specifically, both ends of the first stiffener 125 are connected to the protruding structure 1241 and the retaining rib structure 123, respectively, and both ends of the second stiffener 126 are connected to the protruding structure 1241 and the retaining rib structure 123, respectively. Both ends of the second reinforcing rib 1212 are connected to the first stiffener 125 and the second stiffener 126, and the first reinforcing rib 1211 and the second reinforcing rib 1212 are intersecting. The second reinforcing rib 1212 helps to strengthen the structural strength of the first stiffener 125 and the second stiffener 126. In addition, the first reinforcing rib 1211 and the second reinforcing rib 1212 form a grid structure, which has better structural strength and can further enhance the structural strength of the flat plate portion 121.
[0149] For example, please refer to Figure 12 and Figure 13 The automated external defibrillator also includes a capacitor support structure 7, which includes a constraint part 71 and a fixing part 72 that are directly or indirectly connected. The fixing part 72 is connected to the housing 1, and the constraint part 71 is sleeved around the outer periphery of the energy storage capacitor 3. That is, the constraint part 71 surrounds the outer periphery of the energy storage capacitor 3. The constraint part 71 can reduce the radial movement of the energy storage capacitor 3, improve the installation stability of the energy storage capacitor 3, and reduce the probability of the energy storage capacitor 3 impacting surrounding components when subjected to an impact.
[0150] For example, please refer to Figure 12 and Figure 13 The capacitor support structure 7 also includes at least two axial positioning parts 73, which are disposed at both ends of the energy storage capacitor 3 to limit the displacement of the energy storage capacitor 3 along its own extension direction. Through the combined action of the constraint part 71 and the energy storage capacitor 3, both the radial displacement and the displacement along its own extension direction of the energy storage capacitor 3 can be constrained. This can more reliably hold the energy storage capacitor 3 in the installation position and further reduce the probability of the energy storage capacitor 3 deviating from the installation position.
[0151] In some embodiments, please refer to Figure 12The inner wall of the housing 1 has at least two mounting protrusions 112. The fixing part 72 is connected to the mounting protrusions 112. For example, the fixing part 72 abuts against the end face of the mounting protrusion 112 facing the rear housing assembly 12. Screws pass through the end faces of the fixing part 72 and the mounting protrusion 112 and are fixed to the mounting protrusion 112. The axial positioning part 73 is located between the end face of the energy storage capacitor 3 and the mounting protrusion 112. The mounting protrusion 112 provides a mounting position for the fixing part 72 and can also provide support force along the third direction for the axial positioning part 73, reducing the impact force along the third direction at the connection between the fixing part 72 and the mounting protrusion 112, and improving the connection reliability.
[0152] In some embodiments, please refer to Figure 13 The capacitor support structure 7 includes two separate capacitor supports 7”, meaning the two capacitor supports 7” are two independent components. Each capacitor support 7” includes a fixing part 72, a restraining part 71, and an axial positioning part 73. The two capacitor supports 7” are located at both ends of the energy storage capacitor 3 along its extension direction. The use of two separate capacitor supports 7” facilitates assembly. Specifically, during assembly, the two capacitor supports 7” can be respectively fitted onto both ends of the energy storage capacitor 3 to form a whole, and then the whole can be connected to the housing 1.
[0153] Furthermore, by adopting a structure with two separate capacitor supports 7”, the same capacitor support 7” can still be used even when the energy storage capacitor 3 of different models of automated external defibrillators has different dimensions along the third direction. This helps to improve the commonality rate of components.
[0154] For example, the energy storage capacitor 3 is cylindrical, that is, the energy storage capacitor 3 is a cylindrical capacitor. The constraint part 71 is cylindrical, and the axial positioning part 73 is circular. The radial outer edge of the axial positioning part 73 is connected to the constraint part 71, that is, the axial positioning part 73 is located at the axial end of the cylindrical constraint part 71. The axial positioning part 73 and the constraint part 71 define a receiving cavity 7a with a pick-and-place port. The pick-and-place ports of the two capacitor supports 7” face each other, and the two ends of the energy storage capacitor 3 are inserted into the receiving cavity 7a through the pick-and-place port.
[0155] In this embodiment, the structure of the constraint part 71 and the axial positioning part 73 is beneficial to improving the structural strength of the capacitor support 7”, so that the capacitor support 7” can more reliably constrain the energy storage capacitor 3.
[0156] The constraint part 71 adopts a contour-following design, which can adapt to the outer periphery shape of the energy storage capacitor 3. The two fit well, reducing the probability of the energy storage capacitor 3 moving relative to the capacitor support 7".
[0157] For example, the energy storage capacitor 3 and the inner wall of the receiving cavity 7a are bonded together with double-sided adhesive. The double-sided adhesive has adhesive force, which can reduce the probability of the energy storage capacitor 3 rotating in the receiving cavity 7a and prevent the wires connected to the energy storage capacitor 3 from being pulled or tangled due to the rotation of the energy storage capacitor 3.
[0158] In some embodiments, the front shell assembly 11 is a one-piece structure, for example, a one-piece plastic part. Of course, in other embodiments, the front shell assembly 11 may also be composed of multiple separate parts assembled together.
[0159] In some embodiments, the rear shell assembly 12 is a one-piece structure, for example, a one-piece plastic part. Of course, in other embodiments, the rear shell assembly 12 may also be composed of multiple separate parts assembled together.
